短尾對稱分布序列極值的漸近性質(zhì)
[Abstract]:In this paper, we study the asymptotic properties of the sequence of independent homomorphic random variables under linear normed and power normed distributions, and the convergence rate of extreme moments of short-tailed symmetric distributions under linear normed. This paper mainly includes three parts: in the first part, according to the probability density function of the short-tailed symmetric distribution, the tail expression of the distribution is derived, and the extreme distribution type of the distribution is determined. By the exact expansion of the tail expression under linear normed, the asymptotic expansion of the extreme value distribution of its normalized maximum value and the convergence rate of its convergence to the extreme value distribution are obtained. In the second part, the asymptotic expansion of the extreme value distribution of its normalized maximum value and the convergence rate of its convergence to the extreme value distribution are obtained by using a similar method under the power norm. In the third part, on the basis of the asymptotic expansion of the distribution of the normalized local maximum value, the definition of the distribution moment and the corresponding control conditions are adopted. The asymptotic expansion of the moment of the local maximum of the short-tailed symmetric distribution and the convergence rate of its convergence to the extremum distribution are obtained.
